Blood Vitamin D levels can predict future health risks and death

Free, circulating Vitamin D levels in the blood may be a better predictor of future health risks in aging men, according to a study being presented at e-ECE 2020. These data suggest the free, precursor form of vitamin D found circulating in the bloodstream is a more accurate predictor of future health and disease risk, than the often measured total Vitamin D. Since Vitamin D deficiency is associated with multiple serious health conditions as we get older, this study suggests that further investigation into Vitamin D levels and their link to poor health may be a promising area for further research.

Vitamin D deficiency is common in Europe, especially in elderly people. It has been associated with a higher risk for developing many aging-related diseases, such as cardiovascular disease, cancer and osteoporosis. However, there are several forms, or metabolites, of Vitamin D in the body but it is the total amount of these metabolites that is most often used to assess the Vitamin D status of people. The prohormone, 25-dihydroxyvitamin D is converted to 1,25-dihydroxyvitamin D, which is considered the active form of vitamin D in our body. More than 99% of all Vitamin D metabolites in our blood are bound to proteins, so only a very small fraction is free to be biologically active. Therefore the free, active forms may be a better predictor of current and future health.

Diets high in protein linked to lower risk of death

Diets high in protein, particularly plant protein, are associated with a lower risk of death from any cause, finds an analysis of the latest evidence published by The BMJ.

The researchers say these findings “support current dietary recommendations to increase consumption of plant proteins in the general population.”

Diets high in protein, particularly protein from plants such as legumes (peas, beans and lentils), whole grains and nuts, have been linked to lower risks of developing diabetes, heart disease and stroke, while regular consumption of red meat and high intake of animal proteins have been linked to several health problems.

But data on the association between different types of proteins and death are conflicting.

Living environment may be key to longevity – Study

When it comes to living to the ripe old age of 100, good genes help but don’t tell the full story. Where you live has a significant impact on the likelihood that you will reach centenarian age, suggests a new study conducted by scientists at Washington State University’s Elson S. Floyd College of Medicine.

Published in the International Journal of Environmental Research and Public Health and based on Washington State mortality data, the research team’s findings suggest that Washingtonians who live in highly walkable, mixed-age communities may be more likely to live to their 100th birthday. They also found socioeconomic status to be correlated, and an additional analysis showed that geographic clusters where the probability of reaching centenarian age is high are located in urban areas and smaller towns with higher socioeconomic status, including the Seattle area and the region around Pullman, Wash.

Exercise may slow seniors’ brain aging 10 years

Exercise in older people is associated with a slower rate of decline in thinking skills that occurs with aging. People who reported light to no exercise experienced a decline equal to 10 more years of aging as compared to people who reported moderate to intense exercise, according to a population-based observational study published in the online issue of Neurology®, the medical journal of the American Academy of Neurology.

“The number of people over the age of 65 in the United States is on the rise, meaning the public health burden of thinking and memory problems will likely grow,” said study author Clinton B. Wright, MD, MS, of the University of Miami in Miami, Fla., and member of the American Academy of Neurology. “Our study showed that for older people, getting regular exercise may be protective, helping them keep their cognitive abilities longer.”

New Tool Measures Pace of Aging Across Life Course

A study just released by Columbia University Mailman School of Public Health researchers is reporting a blood-DNA-methylation measure that is sensitive to variation in the pace of biological aging among individuals born the same year. The tool—DunedinPoAm—offers a unique measurement for intervention trials and natural experiment studies investigating how the rate of aging may be changed by behavioral or drug therapy, or by changes to the environment. Study findings are published online in the journal e-Life.

Number of steps per day more important than step intensity

I have written repeatedly about the benefits of walking, calling it the ‘Cinderella of the exercise world.’ Now, according the the National Institutes of Health (NIH), it seems that quantity equals quality in walking.

  • Adults who took 8,000 or more steps a day had a reduced risk of death over the following decade than those who only walked 4,000 steps a day.
  • Step intensity (number of steps per minute) didn’t influence the risk of death, suggesting that the total number of steps per day is more important than intensity.

Doctors often recommend walking as an easy way for inactive people to ease into better health. Taking 4,000 or fewer steps a day is considered a low level of physical activity. A goal of 10,000 steps a day is commonly cited, but recent studies have shown that health benefits accrue even if fewer than 10,000 steps are taken daily. Continue reading

How Well You Age Is All About Attitude, Says New Global Study

Our Better Health

VANCOUVER—A simple shift in attitude could improve a lot for the world’s elderly population, according to a new global study.

That’s because how well we age is connected to how we view old age, the study stated, noting those with a positive attitude toward old age are likely to live longer — up to eight years — than their negative counterparts.

And older people in countries with low levels of respect for seniors are at risk for worse mental and physical health as well as higher levels of poverty, the Orb Media study found. By compiling global data, researchers also surveyed 150,000 people in 101 countries to discover levels of respect for older adults, which varied from country to country.

Canada ranked in the lower third of all for respect, along with Japan, the United Kingdom and the United States.

But one British Columbian expert pointed out that the…

Deaths in middle-aged adults drive decrease in U.S. life expectancy – Study

Americans in the prime of life, age 25 to 64, are dying at a greater rate than in years past, lowering overall U.S. life expectancy, according to a new study published Nov. 26 in JAMA.

Life expectancy — the average number of years a newborn can expect to live — increased in the U.S. by almost 10 years between 1959 and 2016, from 69.9 years to 78.9 years. However, it declined for three consecutive years after 2014, driven largely by a higher mortality rate in middle-aged people of all racial groups.

In the NIA-supported study, researchers at Virginia Commonwealth University analyzed data from the National Center for Health Statistics, the U.S. Mortality Database, and CDC Wonder. They found that from 1999 to 2010, the number of deaths per 100,000 people decreased for all age groups. This decline is attributable to reduced death rates from several specific causes, including heart attacks, motor vehicle injuries, HIV infection and cancer.

Do dog owners live longer? – AHA

As a dog owner, I absolutely have a bias on this subject. Also, I want to credit Learning from Dogs, Paul Handover’s fine blog for first publishing this as a part of one of his posts.

Dog owners have better results after a major health event.

The studies found that, overall, dog owners tend to live longer than non-owners. And they often recover better from major health events such as heart attack or stroke, especially if they live alone.

This is my dog, Gabi, sitting in her basket on one of our rides.

As dog lovers have long suspected, owning a canine companion can be good for you. In fact, two recent studies and analyses published in Circulation: Cardiovascular Quality and Outcomes, a scientific journal of the American Heart Association, suggest your four-legged friend may help you do better after a heart attack or stroke and may help you live a longer, healthier life. And that’s great news for dog parents!

Every minute of exercise affects longevity – Study

Clear evidence that higher levels of physical activity – regardless of intensity – are associated with a lower risk of early death in middle aged and older people, is published by The BMJ Today. But being sedentary for several hours a day linked to increased risk.

The findings also show that being sedentary, for example sitting still, for 9.5 hours or more a day (excluding sleeping time) is associated with an increased risk of death.

Previous studies have repeatedly suggested that sedentary behavior is bad and physical activity is good for health and long life.

Guidelines recommend at least 150 minutes of moderate intensity or 75 minutes of vigorous physical activity each week, but are based mainly on self reported activity, which is often imprecise. So exactly how much activity (and at what intensity) is needed to protect health remains unclear. Continue reading

Gain years keeping heart disease at bay – AHA

Heart disease is the nation’s No. 1 cause of death, killing about 650,000 people every year. Life expectancy is cut short by the disease and the health problems that stem from it. But by how much – and what can people do to take those years back?

Screen Shot 2019-08-11 at 8.55.46 PM.png

For heart attacks alone, more than 16 years of life are lost on average, according to American Heart Association statistics. Researchers estimate people with heart failure lose nearly 10 years of life compared to those without heart failure.

“In the past few years, there have been tremendous gains in reducing cardiovascular disease and increasing life expectancy, but we’ve hit a plateau,” said Paul Muntner, an epidemiologist at the University of Alabama at Birmingham.

Some people are at greater risk than others.

African Americans, for example, are more likely to have high blood pressure, obesity and diabetes, and they live 3.4 years less than their white counterparts. Among the six largest Asian American subgroups, research shows Asian Indian, Filipino and Vietnamese populations lose the most years of life to heart disease – up to 18 years for some – compared with white people.

The risk of early death also is high for people with a history of diabetes, stroke and heart attack. Reporting in the Journal of the American Medical Association in 2015, researchers found people with all three conditions had their life expectancy cut by 15 years compared to those without any of the health problems. Even having just two of the conditions reduced life expectancy by 12 years.

But there is hope. Continue reading

Higher red meat eating linked with premature death – Harvard

People who increased their daily servings of red meat over an eight-year period were more likely to die during the subsequent eight years compared to people who did not increase their red meat consumption, according to a new study led by researchers from Harvard T.H. Chan School of Public Health. The study also found that decreasing red meat and simultaneously increasing healthy alternative food choices over time was associated with lower mortality.

The study was published online June 12, 2019 in BMJ.

A large body of evidence has shown that higher consumption of red meat, especially processed red meat, is associated with higher risk of type 2 diabetes, cardiovascular disease, certain types of cancers including those of the colon and rectum, and premature death. This is the first longitudinal study to examine how changes in red meat consumption over time may influence risk of early death. Continue reading

Growth hormone, athletic performance, and aging – Harvard

Can human growth hormones really benefit aging, like the elusive fountain of youth? In 1513, the Spanish explorer Juan Ponce de Len arrived in Florida to search for the fountain of youth. If he got any benefit from his quest, it was due to the exercise involved in the search.

Few men today believe in miraculous waters, but many, it seems, believe in the syringe of youth. Instead of drinking rejuvenating waters, they inject human growth hormone to slow the tick of the clock. Some are motivated by the claims of the “anti-aging” movement, others by the examples of young athletes seeking a competitive edge. Like Ponce de Len, the athletes still get the benefit of exercise, while older men may use growth hormone shots as a substitute for working out. But will growth hormone boost performance or slow aging? And is it safe?

What is human growth hormone?

Growth hormone (GH) is a small protein that is made by the pituitary gland and secreted into the bloodstream. GH production is controlled by a complex set of hormones produced in the hypothalamus of the brain and in the intestinal tract and pancreas. Continue reading

Higher Fitness Level Can Determine Longer Lifespan After Age 70 – Study

I am always happy to pass along another example of how valuable my eat less; move more; live longer mantra is in daily practice.

Researchers have uncovered one more reason to get off the couch and start exercising, especially if you’re approaching your golden years. Among people over age 70, physical fitness was found to be a much better predictor of survival than the number of traditional cardiovascular risk factors in a study being presented at the American College of Cardiology’s 68th Annual Scientific Session.

best-senior-exercise-equipment-696x469.jpg

While high blood pressure, high cholesterol, diabetes and smoking are closely linked with a person’s chance of developing heart disease, these factors are so common in older people that the total number of risk factors becomes almost meaningless for predicting future health, researchers said. The new study suggests doctors can get a better picture of older patients’ health by looking at how fit they are, rather than how many of these cardiovascular risk factors they have.

Spoiler alert – on being 79 years old

First of all, please read and digest the facts contained in the photo below. I very much believe what it says and live my life accordingly. I think it paints a clear picture about the wonderful organic machines that are our bodies. As such, for the most part, I enjoy robust good health riding my bike nearly every day year ’round here in Chicago.

53086139_10214518369252993_6523680200180367360_n.jpg

Nonetheless, at 79 years old I am not a kid any more. This week I will be going to a physical therapist where I am getting treatments for lower back pains. In between visits to her, every day I do between 20 minutes and a half hour of physical therapy exercises which she has proscribed. I presently am working through some serious lower back pains.

On Friday I meet with a dental specialist who will be consulting on a problem I have under some bridgework on the upper right side of my mouth. That dental structure was put in over 20 years ago and has recently shown signs of age.

While I am not seeing a medical practitioner for the arthritis that afflicts my hands, I rub CBD oil on them regularly and roll Chinese exercise balls around in them to relieve the pain and increase my dexterity. You can read about my experience with CBD oil.

Other than that, President Lincoln, how did you enjoy the play?

I did not intend this post to be as much of a downer as I fear it may be, but I wanted to put out some of the facts of my life that are indicative of a guy who just turned 79 years old. The good news is that I am retired and need to answer to no one for my time.

I am very happy with my life and once this Midwest weather straightens itself out I look forward to being back riding my bike daily.

But, I also wanted to paint a fair picture of things on this side of the temporal spectrum.

Push-ups and heart health – Harvard

Active, middle-aged men able to complete more than 40 push-ups had a significantly lower risk of cardiovascular disease (CVD) outcomes—including diagnoses of coronary artery disease and major events such as heart failure—during 10 years of follow-up compared with those who were able to do less than 10 push-ups during the baseline exam.

“Our findings provide evidence that push-up capacity could be an easy, no-cost method to help assess cardiovascular disease risk in almost any setting. Surprisingly, push-up capacity was more strongly associated with cardiovascular disease risk than the results of submaximal treadmill tests,” said first author Justin Yang, occupational medicine resident in the Department of Environmental Health at Harvard T.H. Chan School of Public Health.

The study was published February 15, 2019 in JAMA Network Open.

Objective assessments of physical fitness are considered strong predictors of health status; however, most current tools such as treadmill tests are too expensive and time-consuming to use during routine exams. This is the first known study to report an association between push-up capacity and subsequent cardiovascular disease outcomes.

The researchers analyzed health data from 1,104 active male firefighters collected from 2000 to 2010. Their mean age was 39.6 and mean body mass index (BMI) was 28.7. Participants’ push-up capacity and submaximal treadmill exercise tolerance were measured at the start of the study, and each man subsequently completed annual physical examinations and health and medical questionnaires.

During the 10-year study period, 37 CVD-related outcomes were reported. All but one occurred in men who completed 40 or fewer pushups during the baseline exam. The researchers calculated that men able to do more than 40 push-ups had a 96% reduced risk of CVD events compared with those who were able to do less than 10 push-ups. Push-up capacity was more strongly associated with lower incidence of cardiovascular disease events than was aerobic capacity as estimated by a submaximal treadmill exercise test.

Because the study population consisted of middle-aged, occupationally active men, the results may not be generalizable to women or to men of other ages or who are less active, note the authors.

“This study emphasizes the importance of physical fitness on health, and why clinicians should assess fitness during clinical encounters,” said senior author Stefanos Kales, professor in the Department of Environmental Health at Harvard Chan School and chief of occupational medicine at Cambridge Health Alliance.
